Other CloudGraph data store library artifacts have similar extensions.įor the CloudGraph HBase data store library use the following artefact. The below dependency is for CloudGraph HBase. Getting StartedĪdd the following dependencies to any Apache Maven POM files (or your build system’s equivalent configuration), in order to make use of CloudGraph classes. Later versions of components may work, but have not necessarily been either tested or confirmed compatible. Note: Components versions shown in this table are those that we have tested and are confident of their suitability and compatibility. CloudGraph supports these component versions: Component Hadoop/HBase EnvironmentĬloudGraph HBase and CloudGraph MAPR-DB require a working HBase and HDFS or MAPR M7 environment in order to operate. Once you have installed the JDK, you’ll need to set the JAVA_HOME environment variable. To check the Java version installed, run the command:ĬloudGraph is tested with the Oracle JDKs it may work with other JDKs such as Open JDK, but it has not been tested with them.
#DATAGRAPH REPAIR MAC OS X#
The latest JDK or JRE version 1.7.xx or 1.8.xx for Linux, Windows, or Mac OS X must be installed in your environment we recommend the Oracle JDK. Data graphs provide rich domain context, change capture and 100% compile time checking against all model entities, relationships and data fields. Results under the CloudGraph service API are mapped to business domain model specific, directed acyclic graph structures called data graphs. This level of abstraction provides several query language options for data stores without a query language as well as the capability to define queries which span or federate multiple heterogeneous data stores. The CloudGraph service API and services are not bound to one specific query language, but to a flexible and granular abstract query model and associated federated query infrastructure, PlasmaQuery ® which supports multiple source query and domain specific languages. For data stores with accessible metadata or schema, CloudGraph services leverage this underlying schema, but for schema-less data stores, the metadata layer bridges any gaps necessary to implement the query and data graph service API.
And rather than requiring every entity in your data model to be represented as a separate HBase table, model entities may be grouped in several ways and entity data graphs may be persisted within one row or across any number of rows and tables, then subsequently queried or “sliced” ad hoc using XPath or a generated Domain Specific Language (DSL) based on your domain model. Under HBase for instance, a Table is a large grained object which may have billions of rows and millions of columns.

General technical background plus architecture componentsĭespite often vast differences between data store physical structure, the rich metadata and configuration layers underlying CloudGraph support the integration of a wide range of vendor data stores while not sacrificing any important characteristics of the underlying product. It uses only annotated Java (POJO) objects as the source of schema or metadata
#DATAGRAPH REPAIR HOW TO#
This step-by-step guide shows how to build a Maven project which generates a simple HBase data model with 1 “wide row” table with example row slice queries.
